What is a rod mill? What is the ball mill ?Rod mill, is to rely on bars for the material grinding mill, wet overflow rod mill is generally used in a material way, the artificial stone sand rod mill, concentrator, chemical plants and power sector in general As primary ore grinding equipment.
The ball mill and rod mill in appearance has a great similarity, which is the main material for crushing equipment, usually in the cement and fertilizer production, the most widely used, with different rod mill is also used for dry mill type of grinding, the main difference is that the ball mill and rod mill which because of its different grinding media generated.
General rod mill grinding round steel bar commonly used rods, steel bars than agree to a short length of 3 ~ 5cm, located at the top of the rod mill conical lid curvature is small and has a smooth inner lining pavement is smoother and more bars in the cylinder body can guarantee the freedom to fall, but also to ensure the rod mill steel bars inside when regular exercise and fall will not fight each other and become distorted. Also due to multi-wet rod mill type and therefore requires larger shot beat mine mouth to ensure the mine mouth will not be blocked, usually it took mine mouth up 1.2m. Although the principle of the ball mill and a rod mill but it is generally similar to the interior of the grinding media due to the ball, the inner liner rod mill than the impact strength as compared to larger and stronger and therefore require a high mill liner strength, but it is relative to the rod mill, ball mill, a wet-type multi-port of discharge is generally smaller and less likely to jam.
